Supplemental material. – 1 male (cl 8.6 mm), 1 ovig. female (cl 8.2 mm) (paratypes; CBM-ZC, removed from USNM 221396 ), “ Albatross ”: stn 5517, west of Mindanao Sea , Philippines, 08 45.30’N, 123 33.45’E, 309 m, 9 Aug.1909 .

Distribution. – Previously known only from the Philippines and off Durban, South Africa, and now newly recorded from the northern part of the South China Sea; at depths of 110- 333 m.

Remarks. – The present material agrees well with the original description of Plesionika kensleyi by Chace (1985). Further comparison with the two paratypes (USNM 221396) confirmed the identity of our specimens with P. kensleyi .

Among the Indo-West Pacific species of Plesionika , P. kensleyi is readily recognized by the short rostrum, which far falls short of the distal end of the antennal scale. In this respect, this species is similar to P. acanthonotus (Smith, 1882) from the western Atlantic and P. holthuisi Crosnier & Forest, 1968 , from the eastern Atlantic. Differences amongst the three species were discussed by Chace (1985).
